What this tool does
Remove unwanted background noise from video or audio files using the FFmpeg afftdn (Adaptive FFT Denoiser) filter. Three strength levels let you balance noise removal against audio fidelity. Video is stream-copied — only audio is re-encoded.
Frequently Asked Questions
What kind of noise does this remove?
Background hiss, fan noise, air conditioning hum, and other constant ambient sounds. It's less effective on intermittent sounds like traffic or barking.
Does it work on voice recordings?
Yes. Use Light or Medium strength to clean up voice recordings without affecting speech quality.
Can I use this on audio-only files?
Yes. Drop an MP3, WAV, or other audio file and it will output a denoised MP3.
Does the video quality change?
No. Video is copied without re-encoding. Only the audio track is processed.
